Stormreach feels like a pretty hostile place with all the adventurers running about in the market, weapons at the ready to carve out the cheapest deal they can.

The /sheathe option already exists, but currently just makes the weapon disappear into some mystical katana-space, most likely that bag of holding the Coin Lords like handing out. Consider the difference if instead the weapons were actually visibly sheathed on characters (perhaps a bit more of a challenge for those greataxe wielding halflings). The artwork is already there, it's just a matter of attaching the weapon at a different point on the character model (back for crossbows, bows, two-handed weapons and waist for longswords, maces, daggers, one-handed weapons). Entering town or any peaceable area could also initiate a /sheathe as a courtesy (and a sign of civilized behavior). The more aggressive types could draw their weapon again with a simple swing or two.

It's not a feature change that's going to get alot of excitement, but it would certainly make Stormreach feel like a safer place rather than an army camp on the brink battle.
