Krynn Ephemeris HTML App

Krynn has always been fascinating for the amount of worldbuilding. Among them, the three moons fo different colors, and, of course, the constellations!

I've always dreamed of providing my players both the night sky and the moon phases of each day, in a precise en predictive way, and until now, all I had, was a way to randomly set the moon phase at the start of an adventure.

So, having a bit of programming skills, I did an HTML app, which can run on any browser, to get my ephemeris:

In the app, you get, for a specific night, both the year-day, the season, the equinoxes and solstices, but also the moon phases (either classic and Taladas) and, best of all, the night sky around 02:00 (2am for the imperial-unitists).

All this can be animated: By pressing either '+' or '-' on your keyboard, you can increase/decrease the "current day", and this will update everything on the graph.

You can try the app in your browser, at the following address:

You can get the ZIP file containing the HTML, CSS, JS, and image files both on Github, and on a GDrive:

For what is worth, the (transparent) image for the constellations I've used is below:

This image is slightly different from the original, as I was more constrained by a circular shape than a page-rectangular shape, as with the original, but the order of constellations is somewhat respected, and I made sure the outer constellations were more or less zodiacal in latitude.

Monk Subclass: The Way of Zivilyn

Preamble: This was posted to Reddit, but for some reason, posting something the evening of Christmas might not be the best idea if you want lots of people to read it.

I'm trying something different for my Dragonlance campaign, and I came up with the idea of a monk following the precepts of Zivilyn, a god of Dragonlance.

The names marked with [temporary] will be changed for better flavored names. Suggestions are welcome.

Behind the scenes, this heavily taps into the "many-worlds" interpretation of quantum mechanics. The monk is able to briefly "visit" multiple possible futures, and then choose the future that align with their aims. The similarities with the video game Life is Strange is coincidental.

Zivilyn is the Krynn's god of Wisdom, able to see the past, and all the possible futures. The god exists both within time, and outside time.

The Way of Zivilyn [temporary] is a Monk subclass in which the monk, favored by Zivilyn, and through meditation, discipline, one-ness with the universe, and mastery of ki, can briefly evoke the divine power of Zivilyn.

Important: Please note that this cannot be used to acquire information. For example, cancelling a timeline where the character learns the name of the traitor means the character forgets the name of the traitor. At the GM's discretion, the character can retain the fact they can learn the information by reproducing the steps, or that a mysterious traitor will act. A good rule of thumb is to make a character roll Intelligence when they want to remember something, with the difficulty increasing with the specificity of the information.

Level 3: Prescience

As you sometimes get brief glimpses of the immediate future, it is exceptionally hard to catch you off guard.

  • You get a +5 bonus to initiative and to your Perception passive value.

  • You can use your reaction to make an attack of opportunity against a creature that moves out of your melee zone even if it uses the disengage action.

Level 6: Superposition [temporary]

By spending 2 ki points, the monk can do two turns instead of one, happening simultaneously, instead of their normal turn, but with the caveat that only one of them is real.

In game terms, the monk player plays two simultaneous turns (with actions, rolls, attacks, etc.), and at the end, must choose one between them: The chosen one becomes what really happened, and the other is cancelled (as if it never happened).

Note: This is alike a quantum superposition of state, collapsing at the moment, selecting the state preferred by the monk's player.

Note 2: A variant of this power might be using as much ki points (limited to proficiency bonus) as desired simultaneous turns (i.e. spending 4 ki points means 4 simultaneous turns, collapsing into one turn only).

Level 11: Déjà-vu

By spending one ki, the monk can have a premonition, enabling them to actually change that future by acting differently.

In game terms, this enables the monk to cancel 1 turn. The play goes back one turn before, but the cancelled turn will replay EXACTLY as it did before BUT the monk can choose to act differently, thus causing what happens after to be altered.

For example, if the party falls into a trap, the monk can spend one ki, and the turn is cancelled, and replayed, but the monk can decide to discreetly stay behind, and thus, all the party but the monk fall in to the trap. Or the monk might warn everyone, and thus, the trap is avoided.

Note: The duration of the cancelled time could be extended by spending more ki (max, the proficiency bonus), which could even extend that to the day, but that would probably make this power too similar with Checkpoint (see below).

Note 2: The cost might increase when using again before a long rest: 1 ki the first time, 2, the second, 3 the third, etc.

Level 17: Checkpoint [temporary]

By spending 1 ki point, and meditating 1 minute, the monk can explore the most probable immediate future (one hour max), and either let that future happen, unchanged, or cancel it. The monk can add other characters to that meditation group by spending 1 additional ki point per character.

In game terms, this means the state of the world is "saved", and the players can play for one hour (in-character time, not real time). At the end of the period (or before), the monk can either decide to accept that future, or refuse it.

Accepting the future means it really happened, and the game continues as normal.

Refusing the future means the game goes back to the moment of the meditation (erasing all events after it), the monk and the other meditating characters wake up, and the game restarts from that point.

This ability can only be used once per long rest of all the meditating characters.
