I haven't thought of anything better than what Grapefruit thought of so this is the gear I suggest for the Black Tower.
- APPAREL -
The Black Tower's members wear a simple, fitted, black, short-sleeved T-shirt with no outstanding markings. A pair of fitted (not tight, to act as a happy-medium between freedom of movement and silence) black leather and fabric pants. The pants would be primarily leather with fabric around the knees and groin to ensure that movement is not restricted at all.
The chosen footwear of the Black Tower is a simple pair of thin, soft-soled black boots focused primarily on muffling footsteps. Members also have black fabric arm-guards that cover the hands and forearms, but leave the fingers exposed. This is solely to minimize cuts and scrapes to the hands and forearms while negotiating rooftops.
Nothing worn by the Black Tower can be considered armor, as it provides no protection from incoming blades and bullets.
- WEAPONRY -
I struggled with choosing a blade for The Black Tower, but I believe the Falcata is a good fit.
It is a one-handed sword with an inward curve and one of the most effective ancient swords.
I suggest that The Black Tower carry this sword in a leather scabbard attached to the thigh.
I considered a hip-mounted scabbard, but those are rather loose and clank around when running.
A back-mounted scabbard isn't as bad, but it would get in the way when rolling.
- MARK OF MEMBERSHIP -
Since The Black Tower's members wear no outstanding logo/symbol, I suggest they have some unique tattoo on their body. However, I'm not sure what tattoo I want for them just yet.
What do you guys think?
EDIT:
Grapefruit came up with the killer idea of having members of The Black Tower have a black tattoo of a rook on their chest, over the heart.
