Pocket Paladin

From BoardGameGeek:

Shadow has fallen over Lorehelm. The Denizens lay defeated. You, a lone Paladin, are what's left of the heroes of the Riverwide Alliance. Mere days remain until the evils of Nul Gador take permanent hold of the crystals. Their plans at the Castle must be stopped before all is lost. You look Northward, squinting against the burning shadow. You whisper a prayer and take the first steps of your final quest. Pocket Paladin is an epic solo overland adventure designed to be stored in a single card sleeve. Work your way across the landscape, interacting with map sites like storms, wandering enemies, Mage and Monster towers, secret tunnels, towns and caravans. Unlock new abilities, recruit allies and learn new skills to be prepared to take on more challenging enemies and--ultimately--the enemy's Castle. Complete your quest before time runs out to lift the cover of shadow and bring peace back to Lorehelm! -description from the publisher
