There is a statue in the front of a woman holding a jar, continuously pouring water. It's clean water and is there for drinking; however, depending on your progress, you might or might not want to. Those who are living basically good lives will find it tastes sweet and clear and cold; for those who are not, however, it is bitter and kind of mucky-warm. It will keep you from dying of thirst, but it tastes terrible.
Within the temple, incense burns. There is an altar for prayer and offerings, surrounded by out-of-season flowers; those who leave offerings or heartfelt prayers (to whomever they wish; the Presence to which this temple is consecrated is all-purpose and will pass on wishes to other gods) and reasonable requests for things other than food and the like may find their request when they return home, if they have been good enough. If not, however, there'll be nothing but a small flower.
Tending the altar is Alma, in simple dark blue robes; she is friendly, but your characters (particularly those who know her somewhat), will notice she is kind of distracted, as if she is hearing someone's instructions. Whose, she can't say.
For the cold weather, anyone is welcome to take shelter in the Temple for up to a week; it isn't particularly comfortable, as it's made of stone, but it's warm. Any new characters will spawn within the temple, where Alma or Orion - based on player's choice - will explain the basics of Purgatorium to them. They have a week to find housing; if they drag on longer than that week, they will find that though they are tired, they will be unable to sleep at all in the temple. Once two weeks have passed, they'll find they can't enter at all past sundown. This will last for two weeks before they can enter again.
This post is to be used ICly. The Presence - or, sometimes other Powers within Purgatorium that characters may not be aware of - will grant requests if an acceptable offer is made in exchange.
Requests may be made using any variation of action tags. Have your character leave something within the Temple while making a request and they will be rewarded with an item on their bed when they return home. Neither Offerings or Requests necessarily need to be material possessions, you're character is free to ask for whatever they want, although there is no guarantee that they will get it. Feel free to be creative with this, but keep in mind that each request will be weighed against your character's offer.
A mod will answer all comments, informing you what your character will find on their bed when they return home. Make sure requests are clear, as sometimes you may find something unexpected in place of your wishes.
