The days on Ryh are longer than those on Earth. Yet somehow it was still 33 rotations before we encountered the Oxataya - another 12 before we met any Ahzuri. So far our negotiations have gone well. Oxataya are an ancient water-dwelling clan, full of wisdom, knowledge and insight. Ahzuri are an ascetic mountain tribe of which we still know very little. We have learnt a lot from Oxataya, and their temples, but there is still much to discover. Our new research outposts and specialists have shown great promise so far. Still, only time will tell. The Specialists Expansion adds two new local factions for players to negotiate with, a temple location to visit, and outpost boards to extend their research bases. It also adds a lot of new characters (variable player powers) and contract cards, and the new, powerful specialist dice. —description from the publisher
