Best rules question in a long time tonight, posed by our youngest Thursday 40k regular Argo.
"Does a Relic held by a model embarked in a Night Scythe go into Reserve with the model holding it after the Night Scythe inevitably crashes?"
Really, RAW doesn't address this specific situation at all, so it could go either way.
The ruling, made by Sam after ten minutes of poring over books, is that the Relic could not be placed "reserve" space as it is effectively impassible. So we follow the procedure for the Relic ending in impassible terrain and then scatter the Relic 1" from the vehicle.
So a question and an answer.
Edit: Whoops, missed an important "not" in that explanation.
