Lol. You can't *walk* to the void, you have to get their via the plot. WARNING, spoiler below. Spoiler To get to the void you need to get down to the south via a boat (buy one or use Stringy Pete's), and then wander throught the wilderness to the Resting Place of (I forget his name) he's still alive, and will go to the Ring of Stones by the Rosenburg (sp?) and will teleport you to the Void once you have the Vendegrothian Machine.
Major lowering of alighment. Two fate points you could get, but won't. Loss of an extremely useful follower (if you are tech) and a formidable fighter. Relief from Magnus' whining every time you hit a good guy- or someone who he thinks is a good guy.
