The Daemonette Morrslieb upgrade states as follows:
When you summon a Daemonette into a region, you may take control of an opponent's Cultist in that region until the end of the turn.
In a recent game the following scenario happened:
Nurgle has a single cultist and no other follower in Kislev.
Slaanesh summons an upgraded Daemonette into this region, taking control over the Nurgle cultist.
Since the Nurgle player has no followers in the adjacent regions, is he still able to summon a figure to Kislev?
We debated a while how to interpret the effects of "take control".
The rules state, that to summon a follower...
...the figure must be placed in a region where that Chaos Power already has a figure, or in a region adjacent to such a region.
So, how can "A player has the figure in the region" be interpreted in this context?
1. A player has control over the figure in the region.
2. A figure from the original follower set of the player's Chaos Power exists in the region.
In the end, we democratically house-ruled (3 to 2) for option 1, reasoned that the Nurgle player has lost control, and therefor cannot use its cultist as an anchor for summoning more followers to Kislev.
Since the question is far from being simple to answer, what does the board think?
