For all intents and purposes, Irminsûl is the centre of the universe. Like a great whirlpool, it draws power to its shores, to be absorbed or destroyed.
People come to Irminsûl for many reasons, but the most common one is this: power. Only in Irminsûl will you find sorcerers rubbing shoulders with shapeshifters. Only in Irminsûl will you find great swords of ultimate destiny sold in flea-markets.
And only in Irminsûl will you find people you can call your equals.
