Born in Sigil, raised in Sigil, Spider quickly learned how to take care of himself. It's not that he didn't have parents or friends, it's just that in the Cage you can't really trust anyone but yourself. At least not in the long run. Not being the biggest kind on the block, that meant he had to find another way to survive than fighting and since he was pretty agile, he became a decent thief. He didn't like the idea of trying to take things from peoples pockets, too risky and to little profit, so instead he learned how to pick locks and climb walls to get into houses. He grasped the climbing part very well, and from that he got his nickname. These days no one, except maybe his parents and himself, remember his real name.

Being a bit too curious by nature can get you into trouble, especially in Sigil. This Spider learned the hard way. Getting caught once too many reading in the act becuase he just had to see what the next room had to offer (when his bag was allready full) made him a hunted man. He never got caught, but his description started circulating and it was just a matter of time before the Mercykillers started paying him attention. At that time Spider figured that Sigil was a bit too hot for him and left. He followed a caravan through one of the portals and ended up in Bytopia. There he met a Illusionist named Gra'ak and they quickly became friends. Both being cagers by Origin, they had the same view on life. Neither of the two were inclined to return to the Cage any time soon for reasons they never told eachother (as I said, they did have the same view on life) so they traveled the Planes together, just to see what was out there.

Through their travels, Spider grew more and more fascinated by Gra'aks use of the Art. So fascinated he decided to start learning them himself. This did not pocessa problem since Gra'ak was a willing tutor. They traveled together for two years and all the time Spider was getting better and better at magic. Finally he and Gra'ak both realized that he was progressing fast enough to not need Gra'ak around much longer. Again, both being Cagers, they knew better than to count on old friendship meaning anything and decided to go separate ways before one of them would find a knife in his back. Gra'ak kept exploring the planes and Spider returned to Sigil, figuring it was safe enough now. To say that he was homesick would have been a lie, but nonetheless, he wanted to return to the Cage. Once a cager, always a cager.

He had enough riches from his traveling with Gra'ak to get a small house for himself. Actually he could have gotten a bigger house, but he didn't want to draw that much attention to himself, he knew all too well that thieves prefer the bigger and fancier places. However, settling down and taking it easy is just not his style and it is only a matter of time before he'll get himself into trouble again.
