The Show Must Go On

This is a scenario for Runequest characters with skills between 50% and 75% and little Rune magic, or AD&D characters of 4th- 5th Level. Statistics are given in full for the Circus troupe, who can be played as PCs by the party, or run as NPCs, though they should be essentially non-combative.
Stats for the other major NPCs are also given at the back of the adventure.

INTRODUCTION
Ghararna is a prosperous little village in a fertile valley, surrounded by mountains on one side and steppes on the other.
However, a Horde of Barbarian Nomads have recently arrived in the area: they took three hostages from the village to ensure obedience, and are planning to stay for the winter. Worse still, they plan to attack a nearby tribe of non-humans, the Karagol, in the mountains near the valley: they have captured a leader of the tribe, throwing the Karagoi into confusion.
The villagers have had good relations with the tribe; they fear the coming war will destroy the friendship. Also, the likely battleground will be the villagers' fields, destroying the unharvested crops that are vital for surviving the harsh winter.
To counter this threat, the village elders have pooled all their resources to hire the party: their objectives are to make the Horde leave without carrying out any reprisals against the village, to rescue the hostages, and to ensure the tribe do not attack the village.
The villagers have also paid Sravindly, the boss of a travelling circus, to take the party into the camp as part of the circus: the circus will give what aid it safely can.
Once in, the party can learn what the Horde is like and decide on their course of action, either acting immediately or after the circus leaves.
