The girl steps aside, seemingly human, possibly with a fiendish lineage of some kind.<br/><br/>"Much appreciated, I simply don't know how to deal with such things, and I'm fairly certain that it is set up to be instantly lethal."<br/><br/>Carefully looking at the hinges, and around the frame, it soon becomes clear that there is a small gap, one that a particularly thin blade and mechanism could indeed be stored inside. Running a piece of wire along discovers the presence of a curved blade, and a few small bolts of metal to hold it in place. By the pressure, it seems to be spring-loaded. However, with a bit of effort, and holding the door closed while she works, Alaedra is able to unhook the spring, causing it to fall to the ground harmlessly. Jamming a piece of hardwood in for safe measure, she can open the door... and nothing happens. The trap has been safely disarmed.<br/><br/>"That's really quite impressive."<br/><br/>(The natural 20 on Disable Device brought your total to more than double the number needed, so really, you could dismantle the whole trap and door ifyou wanted, or disconnect the trap and take it home. But there's probably a form for that *wink*)
