Eidolon – Æther
Æther is everything. In the game it represents everything your character can do, it measures your ability to continue existing, it allows you to roll dice, it acts as currency, its spent to use special abilities, and its gained in numerous ways. Eidolon is, in a way, resource management and Æther is your sole (or, if you will, soul) resource.
If you run out of Æther then your Conscience drops a point and you get ten Æther. You also fade out for the rest of the scene, the ghost equivalent of being knocked unconscious. Your character can never die from Æther loss, but running out of Æther can remove you from the action for a while.
You are never limited on how much Æther you can have but since its gained and lost so quickly and often we suggest using tokens to track Æther at the table and only recording it on your character sheet for between sessions.
Since Æther can be held in vast amounts there are a handful of ways to track it via tokens, the easiest being with pennies. Think about it, you can get 100 tokens for a dollar. You could also use poker chips, White = 1, Red = 5, Blue = 10, Green = 25, and Black = 100 for example. Another suggestion made to me was Hell Bank Notes, Hell bank notes are a form of joss paper, an afterlife monetary paper offering used in traditional Chinese ancestor veneration. However you track it, it’s important you keep track. Player’s who don’t keep track of their Æther loose it, the simple rule being that if you’re not sure if you have it, you don’t.
One of the most common ways to spend Æther is to roll dice. If you don’t have any other means to gather dice you can always spend ten Æther to roll a single die. Remember that most of the time you’ll need to reach a total ten, a single die won’t likely do you any good.
There are a couple mechanical methods for gathering Æther, those are covered later, but its worth mentioning the easiest, fastest, and best way to get Æther: from your Game Master.
ATTENTION GAME MASTERS: Reward your players with Æther points! What should you reward? How about being a ghost, making decisions based on character perceptions and not player perceptions when its detrimental, doing anything that adds to the game’s fun or cool, and most importantly reward them for getting involved in your game. Someone gives you a journal entry in-between sessions? Five Æther points! Someone describes a brilliant interaction? Ten Æther! Æther is not only the character currency but also the GM currency and you should give it to your players when they do something you like.
