Does anybody know what time the bondfire is open? And what does it do?

The bonfire was for a holiday event. You can read more about it here: http://subeta.net/subetapedia/index.php?act=ventry&id=92

It will probably open around November. :) And, if I remember correctly, you're suppose to throw in fireside things into the bonfire and you get prizes. :D

It's part of a fall festival here on Subeta. If I remember right, it happens in September/October/November, and if it's like last year you throw Red Rreign items into the fire to receive gifts and blessings in exchange.

Huh. Interesting. Thanks! ^^
