As the title suggests--does anyone have directions? I'm sure it would be helpful to post them in one place so we don't have a few hundred people asking repeatedly.

Please post them here if you've got them.

It is on the continent Furnachia.
Go to Arelium church and 'portal rilynttar'. Rilynt'tar is on Furnachia. Walk out east gate and then follow road to south. Lords of Chaos guild is a bit south by south east, near the road. It has the same sword-shaped mountain configuration south of the guild entrance.
