Welcome to the youngest and most turbulent of the Realms, a mountainous expanse known as Tirna'Cel. This place was once well known for its power mongering warlords, magic wielding Sorcerers, and archfiends from the deepest pits of the Abyss. But in the last six hundred years, this has changed. Tirna'Cel is a peaceful and welcoming land now, doing no small part to the efforts of the warlord Tirna'Gael, a member of the lands founding nobility. Tirna'Gael turned against the other rulers without warning, attacking and overwhelming them without remorse. He is said to have suddenly grown stronger and more powerful. The reasons for his remarkable gain in power unknown, so they are routinely connected to items believed to have been entombed with him by the then newly-formed paladin's Order of Garadon. After his death, Tirna'Gael body was interred in his central citadel, a large stone fortress suspended over an immense lava pit. There he is rested for nearly six hundred years, protected by the surrounding hostile environment and a small cadre of supernatural guardians summoned and permanently bound by the Order of Garadon. But recently, rumors have reached the corridors of Tirna'Cel's capital city that invaders have struck the fallen heroes burial place, in search of one or more of his legendary magic items. So far, all that is known of these foul creatures is that they are native to the environment, being resistant to the fiery dangers of the area. Your party has been summoned by the Lord of the realm, who has charged you with ending the threat to Tirna'Gael's tomb and the potential destruction of the lands long enduring peace. If the sources of Tirna'Gael's power were to fall into the wrong hands, it could mean the end of the nation as you know it.

The invisible enemy. Rats, cats, and double-drats. Six months ago, the residents of Luskwald heard rumors from passing merchants of a possible goblin incursion into the region. News from the nearest city confirmed speculations that goblin tribes were massing in the distant hills. Worried about the future of his small community, the Laird of Luskwald commissioned a stonemason and several carpenters to rebuild a damaged keep two miles north of the village. The repair crew worked for weeks restoring the keep's fallen walls, while waiting nervously for the first goblin to show its ugly head. For the first several days the restoration proceeded according to schedule, but in the weeks that followed several 'accidents' led many to believe the keep was cursed or haunted. In the past week three of Luskwald's villagers have died, each the victim of a grisly assassin whose identity remains a mystery. Several citizens have heard or seen peculiar things over the last several days, leading them to believe that Luskwald has been cursed, or worse, ravaged by angry spirits--perhaps sent by a greater evil that dwells within the ruined keep!

Goblin attacks have always plagued the farmers and merchants who live and travel along the roads leading to Whitesparrow. But a recent rash of new attacks are something different. The goblins of one particular tribe have gotten particularly smart, attacking with careful tactics and cunning ambushes. The village guards haven’t been able to outwit the goblins, even when laying traps of their own and hiring mercenaries to stop them. Even as goblins go, Rosethorn isn’t much to look at. He’s small and runty, and yet a lucky break placed him in charge of the Brownleaf goblin tribe. When he claimed a powerful magic relic from a dead wizard three months ago, Rosethorn found his intellect multiplied many times over. The world began to make a more intricate kind of sense to him, and he saw patterns in the ways other folk traveled the roads. After hiring a spy in Whitesparrow to tell him which wagons to pursue, Rosethorn cunningly bribed the wagons’ guards to throw battles in the goblins’ favor. He then moved the lair of the Brownleaf tribe away from their dank caves and into the ruins of the Bearded Man—an enormous dead tree at the center of the Howling Wood. There, Rosethorn continues his campaign of ambush against the foolish villagers, increasing his wealth and power with each robbery.
