Hyperborea, "Ghost Ship of the Desert Dunes"

I'm looking for 1-2 additional players to join my current group to play through an adventure for the Hyperborea rpg called Ghost Ship of the Desert Dunes. The Hyperborea rpg is a sword and sorcery OSR game that is probably most similar to D&D 2E. The setting is a human only setting (as far as PCs go), and in lieu of multiclassing, the game has a variety of fun subclasses for each of the four traditional base classes (e.g., Runegraver, Warlock, Cyromancer, Cavalier and many others). The adventure is for characters level 2-4, and will likely take 4-6 sessions. If it goes well there may be opportunity for additional adventures in the future.  The time slot for this game is 8:00 pm EST on Fridays, and unfortunately that is non-negotiable. I'm looking to run session #1 on February 15.

This looks interesting.  Will everyone be the same level?

I would start everyone with the same amount of XP. However, since classes advance at different speeds (As per old school D&D), it is possible that one character could be different level than another. 

Is there a quick start or PHB?  I am experienced with a lot of systems, but this would be a new one for me.
