Scope (Book 1)

North Road → goblin cave → Fallcrest / Blue Moon → Hammer manor → waterfall climb → Ethium plateau → ruined tower → Garnel → healing pool.

Open threads left for later books: east dig, castle hill, black dragon, Maelis Varn, Mala’s book, cloaked watcher.

Player role

Second person. You are Thorn Axehand (half-orc fighter). Your companions — Derek, Dave, Nibbles, Loki — travel with you unless a passage says otherwise. Choices are yours; companions react in the prose.

Tone

Same as the novel: Fighting Fantasy for ~12+, warm, clear, silly-but-earnest. Combat is exciting but not graphic.
