It's acceptable to pray from wherever you want for IC reasons, as long as you don't spam it or expect to get a response every single time. The role command is an excellent tool that can be used to track significant places and experiences in your character's life, and can be written in the form of "prayers" as well if you are talking about longer prayers to Amaranthe (or any deity for that matter). `

Wednesdays (only starting next week, not this) are the only time I have any kind of guarantee, and even then not always. Wednesdays are the only time I have any kind of regular person watching my young daughter besides me, and many evenings I have other things I need to do, so most any other time is random. Sorry.

If I do see a long record of prayers and notes and a role and whatnot, I do make the effort to make an appearance or other arrangements during your usual login times.
