PFS 1-05: Trailblazers’ Bounty by Tineke Bolleman
For levels 1–4 (Subtiers 1–2 and 3–4).
The powerful nation of Cheliax has posted a public bounty that would richly reward the first team of explorers to chart a viable route across the Menador Mountains, linking the nations of Isger and Molthune (all to bypass the economic powerhouse of Druma, which has recently imposed higher taxes on key goods crossing its borders). Yet the Menador Mountains are an imposing obstacle, replete with steep slopes, snowy peaks, and territorial orcs. Even so, there are no finer explorers than the Pathfinders, and the Society has dispatched a team to collect the prize.
