Eltharodo.....what/who are you talking about? There
are no Traps in Spellhold at all, except for the single, nondisarmable "Crushing Walls" trap. Greyhand ovbiously did not get out of Spellhold in the same way the party did, because he would have had to:
1) Get sent into the Maze to begin with (neither Irenicus nor Bodhi had much reason to do such a thing)
2) Kill a bunch of Kobolds (even this would be difficult for Greyhand, unless he had a party and he was just the only survivor)
3) Get past some Undead (impossible if there's a Lich)
4) Kill Dace (impossible unless at least one of Greyhand's party was a lot more powerful than Greyhand)
5) Kill or sneak past some Umber Hulks/Minotaurs/Yuan-Ti
6) Somehow, bring the Kobolds, Dace, and anyone else they killed back to life (impossible)
7) Somehow get that giant stone head to snap shut again
Get past whatever Trolls and Minotaurs are along the way to the two stone Horns you need to fix the statue
9) Somehow get around the fact that whoever sent Greyhand into the Maze probably isn't just going to let him walk right out
10) Either A] Answer all the riddles correctly and fight some Trolls, or B] Answer some riddles incorrectly and fight Sahuagin, Otyughs, Elementals, and a Mind Flayer
11) Once again, somehow bring back to life everybody that he (or they) had killed.
Once again, Greyhand did
not go through the Spellhold Maze. And what does his age have to do with anything?
The tricky part is figuring out what Greyhand
did do, and when. He didn't stage his jailbreak during the chaos caused by Irenicus killing all the Cowls, because then Grey wouldn't have come under Jon's direct control and thus developed a grudge. He's already out by the time the PC arrives, so that can't have caused it.....maybe when Bodhi arrives, she's hungry (I suppose eating madmen is better for society than eating able-bodied seamen), and stages a hunt to amuse herself--and Greyhand manages to lose himself in the shuffle. Still, even this doesn't work well, as his dialogue doesn't mention Bodhi even once.
