If Dawn uses Brisk Effulgence (Each ally in Citizen Dawn's line of sight may sprint.) and Proletariat has Sickle Formation in play (Whenever a Proletariat sprints for the first time each turn, all other proletaraits may sprint.), and there are three Proletariats in Dawn's line of Sight, do they each get to sprint three times for nine total Proletariat sprints?
If so, if Proletariat A and Proletariat B are both in Dawn's line of sight and then Dawn has Proletariat A sprint, which allows Proletariat B to sprint, and Proletariat B then sprints to a hex that is NOT in Dawn's line of sight, does Dawn still allow Proletariat B to sprint again?
Also, if Proletariat A is in Dawn's line of sight, but Proletariat C is NOT in Dawn's line of Sight and then Dawn has Proletariat A sprint, which allows Proletariat C to sprint to a hex that IS in Dawn's line of sight, does Dawn then allow Proletariat C to sprint?
