Well, the Gaesatae tribe were the only Celts who were recorded to fight naked. This Roman writer described them in so much detail that i had to boil it down to this:
Bro. Imagine Bor draped in a bearskin, axe in hand, viciously bellowing a tribal war cry while waving his bloodstained two-bladed axe and his shield painting of a red bear adorned with broken arrows.
I'm thinking of a theme song for Bor. Probably something Celtic. Bor is adaptable and flexible to change, but he can never succeed without his memories and roots.
And, uh, okay, chuk. Yah. I'm still a DnD noob by some people's standards.
The Guildmaster paced around, his eyes fixed on the girl. "Another Arcarti? The last time a Scout passed through here was a week ago." He paused. "He gave away the location of one of our safehouses to... questionable men. We turned him over to the guard, but he tried to escape. I proudly announce that he is now lying at the bottom of the harbor with ten to fifteen arrows in his back." A moderate chuckle resounded throughout the warehouse. Even Adrian let a smirk manifest on his face. "As for your second question, I can only imagine that you might be an agent for old Bardy or another of our 'questionable men'." The Guildmaster inspected her closely. "I have another question for you. What the hell is your kind doing in Mullen?"
Actually, I can't find a single store near my location which sells DnD merch, so I'm forced to d-load PDFs of the core rules and fantasize about actually playing it.
