300 (+75 disads) so 375 total points.
I used the Scout template from Dungeon Fantasy 1 (with slight tweaks for a desert themed character) and the Elf template from Characters (with slight tweaks for a Desert Elf).
I don't know anything about the Banestorm setting. Do desert-specific elves exist? Do they have a culture separate from forest-dwelling elves?
Also, what languages are typical for the area?
In terms of the roles mentioned, my character covers the Ranged Attacker role very well and the Thief role pretty well. I imagine a backup in the Thief regard may not be a bad idea (or a regular Thief type). I have a few spells that are intended to aid in desert survival.
Your characters sounds very well rounded.
Unfortunately there is no such thing as a Desert Elf in Ytarria....Even in places where elves are normally found, they are still rarely seen.....that is unless you REALLY pissed them off!
Consider:
High Elf (More like an Eladrin)
Wood Elf (The classical Elf....sometimes confused with a Dryad)
Dark Elf (The Drow)
Savage Elf (The Grugach or Valley Elf)
Water Elf (Often mistaken for a Nymph)
Grey Elf (The Lost Tribe....on the edge of TL4 in some respects but NO gun powder!)
Half Elf (Self explanitory)
Banestorm is a game world but initially refered to a very ancient and powerful spell that backfired in the worst possible way.
It opened up portals to other alternate realms and pulled the indigenents to the spells place of origin....similar to the catastrophic Drow magic that turned the Seul into a wasteland.
Banestorm on Y'tarria...also known as planet Y'rth to those with a 1st edition copy of GURPS Fantasy...now manifests as a massive disturbance off the southern coast of the main continent....it is no longer mobile but shifts from time to time....and every now and then something arrives that was never previosly recorded...but for the most part the magic is still POTENT and DESTRUCTIVE as the day it was cast but it has since "stabilized".
It brought humans from all over earth history as well as dwarves, elves and the whole cornucopia of fantasy folk to this one world....near as anyone knows...NOBODY on Y'rth has decended from a person ACTUALLY from this planet....only decended from someone who had arrived against their will....in most cases.
They invention of gun powder has occured a few times but was ALWAYS suppressed violently if nessarry by the mages of the world....except for the Dwarves....who have developed limited ability to create musket style weaponry (TL4)....the Mages refuse interfere for the Dwarves seem content only to use it to keep the orclands at bay....so for those who want to shoot.....be a Dwarf.
As for languages....it is in the "muslim" portion of the world, so arabic or farsi are common place but so is Anglish....the worlds variant on common.
Similar to english but with a few french and spanish and even latin root structures involved on top of classical english....(Defaults to English-2 for parachronozoids)
Many eras that were not congruent on their respective worlds now co-mingle on this world.
Norman Francs and the Hordes of Genghis Khan now Co-habitate in some places for example.
Dominant faiths of Y'tarria are Catholisim, Islam, Roman.(more like Ceasars time than the vaticans)...plus the various non-human beliefs.
Magic can be rare in some places and powerfully abundant in others.
The Islamic areas are mainly mana low.
I will be lurking if there are any other questions.
Peace & Light (and the musical score to Blackhawk Down will serve the purposes of this foray rather nicely I think)
