Nothing else is found or heard. So, behind door number 1...
Is a hallway that goes 50 ft before turning left, angled downward. There isn't any illumination then the outside though, so it's very shadowy at the turn.
(For a fighter, you're acting distinctively roguish. Don't forget, characters have max HP per level. Also, neither one of them are particularly skilled classes. Not trying to convince you, just commenting. Okay, maybe a little. I'm one of those party balance guys. Plus, flanking with Irvine will mean lots of damage in little time.
In my opinion, there are 5 levels of caution in D&D. Barbarian: 'Traps? There are no traps. Even if there were, I'd break them!', Fighter: 'If they happen, we'll survive, but try to avoid them.', Cleric: 'This looks suspicious. I'll cast Find Traps to be safe.', Wizard: 'Hmm, if I were an enemy, I'd place a trap here.', and Rogue: 'Look everywhere. There's always a trap. Always. Sometimes it's hidden... by another trap.')
