Obviously I've got to do descriptions for Freggo (unless Goken responds which he's not done so far), Kali and Magnus.
Below is my impression of all three, please add or subtract as you see fit, is this what you see when you imagine each of the three-
Magnus-
Thick set Male Dwarf Fighter wearing Scale Armour, a Heavy Shield and Warhammer close to hand- if not in hand. A flame-haired mad-Dwarf, lover of the booze, he should have a tankard or something similar attached to his belt or likewise close to hand. Magnus ticks all the boxes for your stereotypical Dwarf Fighter- tough as old boots, grizzly, a short-fuse, an explosive temper and big on hitting things till they go away. All of his kit (armour, warhammer etc.) is begged, borrowed, stolen, broken once or twice and then fixed up with whatever is at hand- it all works of course but it doesn't look great, or heroic.
If he were not an adventurer someone spying him would think him a bum, a drunken bum at that.
Freggo
Male Human Swordmage. Sandy haired, white but tanned and with a toothpaste smile, six foot tall and lean but muscled (he looks the hero). Luke Skywalker without all the moodiness, arrogance and deep thinking. Freggo is beyond confident, and yet is never boorish- he's jolly, and decent, and nice, and clean-cut; you know he loves his mum and dad- he stops traffic to let old ladies cross the road. He wears a nice (new?) suit of Leather armour, wields a longsword- likewise new, with a pair of javelins in a sling/holdall on his back.
He's new to this hero lark but is an eager puppy, knocking things over as he makes grande heroic gestures and remarks before throwing himself in to the battle.
Kalimaru (Kali)
A Male Razorclaw Shifter (I'll provide a picture of one if you can't find one). Big (six foot tall but looks bigger), heavily muscled but lean and mean (a brute of a man/beast), with a thatch of black wild hair- and beard. He wears Hide Armour- the cured hide of some beast he killed with his hands and teeth (a low level creature), a battleaxe in one hand and a hand axe in the other. Longbow quiver and arrows on his back. Everything he wears and owns has been made specifically to do the job it is employed for- nothing he owns is new. He or his clan manufactured everything from whatever was in the wild that would do the job, he is after all a Ranger, a wildman, a silent killer. His apparel would most probably has tribal markings and is dyed to camouflage the silent hunter.
A deadly brute, with all the right tools- he looks like might eat you rather than shake your hand.
Just impressions I formed along the way. I'd be happy for any alternate opinions.
Cheers PDR
