While trying to decide what class to make for a second character I noticed this rp focuses heavily on the class system from Path of Radiance though there are still differences. Below are class options that are not available in this role play that are available in other Fire Emblem games (English games only). It might be important to note these differences on the OP or to explain that this game is using the class system from what ever game you used. 

[hider]
Tactician, Conqueror, Dread Fighter, Bride.
Trickster, War Cleric, Griffon Rider, Dark Flier, Dark Knight. 
Hunter, Ballisticians, Chameleon. 
Vanguard, All Tier 3 Promotions (Radiant Dawn). 
Summoner/Necromancer, Wyvern Knight 
Manakete, Taguel. 

Sword/Lance/Axe Knight cannot promote to Great Knight. 
Priest/Cleric cannot Promote to Sage. 
Shaman cannot promote to Sage. 
Monk cannot promote to Sage. 
Mage cannot promote to Mage Knight. 
(None of the plethora of possible class promotions from Awakening or Shadow Dragon)

Nomad and Bow Knight are the same. 

Sages cannot equip Dagger/Knife. 
Dancer cannot equip Dagger/Knife or Sword. [/hider]
