Would you mind terribly if I contributed some flavor text for the classes and races that have none? They're rather bare, and it always bothered me a little on the select screen.
Here's something for the Star Elf, Starslinger, and Moon Paladin. You may use or change it as you please and I welcome any input.
Distant cousins of the Shalore, Star Elves have close ties with the Wintertide moon. They are completely nocturnal, a quality that during the Spellhunt would result in most of their race being mistaken as evil entities. What few remain spend their time in hiding within the shadows of the night.
They look to the stars for guidance and blessings. They possess the Shadow Swell talent which allows them a boost of evasion every once in a while.
EDIT: Here's Starslinger (I am assuming that both classes hail from the Gates of Morning as opposed to Midnight, as Sunwall is the starting point.)
Starslingers hail from the Gates of Morning, the last bastion of the free people in the Far East. Their way of life is well represented by their motto 'The stars are our guidance, our light, our protectors. When sun and moon fail to shine, we alone are the last lights of salvation.'
They can channel the cosmic power of the stars into their ammo while unseen by enemies, destroying all those who seek to destroy the Sunwall from afar. They can lay down magic sigils of darkness, trapping enemies before they have any chance of attacking.
Their most important stats are: Magic and Cunning
EDIT 2: Moon Paladin. (I intentionally took the last part of the motto from Sun Paladin because they are both, well, Paladins. Not sure if that's the best idea.)
Moon Paladins hail from the Gates of Morning, the last bastion of the free people in the Far East. Their way of life is well represented by their motto 'We stand between the moons, to whom the Sun gives power during the blackest of nights. We are the stars that shine even when the sun is dim, and against our strength none shall pass.'
They channel the power of Eyal's two moons, Summertide and Wintertide, with their dual weapons to rend any who seek to destroy the Sunwall. They can protect and harm with the power of the moons and stars.
Their most important stats are: Dexterity and Magic
