Mytharria is a Neverwinter Nights persistent world, based in an original universe not associated with any particular fiction. It has its own pantheon; some of the deities (e.g. Freya) resemble those from other pantheons, others do not. It exists in both Neverwinter Nights and Ultima Online flavours.
Mytharria is a low-magic world heavy on the roleplay. Higher-level magic items (generally any weapon or armour with a greater than +3 bonus) are uncommon. Some spells are nerfed. Out-of-character chat is restricted to tells and party channel, and in-character talk is expected to be period based. Character death uses a fugue plane system, although the penalties are not high. There are currently no custom races or classes.
Mytharria is all about roleplay. Read the forums for a taste.
