An hour may not be enough realistically speaking if you've never played, but either or will do, I have time 04:00 GMT as well as an hour before session. Do you have a basic idea of what you might want to play?
The basic premise of the party is pretty much that they're on the run from a conquered kingdom that's pretty much an expy of medieval Flanders and are seeking allies to reconquer it from an expy of Rome. They've just arrived at Elfland. It would be easiest to fit you in as an elf, but that doesn't mean you need to be. Just know that 1. halflings don't exist, 2. gnomes are close to extinct, and 3. elves are all-female.
The current party, in case you want to build towards it, consists of
1. Teutomate, socially awkward, former hikkiNEET, but prettyboy prince who's the actual candidate for a restored monarchy. Dedicated lightning element blaster and healer.
2. Lachrymarum, big titted oni girl who's even more socially inept but likes talking too much. Dedicated front-line controller with lots of HP and melee ability.
3. Matilde, former trader in charge of finances. Jewish as hell and often too Jewish for her own good. Generalist mage with a gun.
4. Gyliam, dedicated necromancer from the neighbouring Cessan republic, an expy of Switzerland. Has a giant skeleton that chicks don't dig, but he acts like they do.
