I'm joining!
Tribe Name: Tartes
Cacique Name: Mikael
Colour: Dark Green
Location: the mouth of the river to the east of Lucea (don't know how is it called IRL, if we can change the names then it's called Tar River)
Magic User: Tonai the Fire-Freezer
Magic Spell: Freeze: it throws a ball of pure coldness that, in contact, freezes the objective. In living beings, the temperature drop might kill them. (1 MP)
The Tartes people are excellent fishers and navigators, second only to Mesaqoo's tribemen. They are also able to craft many weapons from the animals they fish and hunt: an animal's rib cage, combined with leather, makes an excellent armour and shield; fish's spines can be added to stone-point arrows or to axes for maximum damage to the enemy; and the claws of jungle tigers are given to melée fighters so that they can defeat the opposing soldiers with more efficiency.
This would be my banner:
It's a representation of what would be an island: a mountain in the center (brown), jungles surrounding it (green), plains (yellow) and a beach (red (for red-coloured sand)) surrounded by the sea and traversed by rivers (watery blue).
