Trireme are safe near coast, but polar zone are a danger place, and pole are 
not a real coast. 
In classic topology the pole are very long, this simulate the difficult to 
navigate in the polar zones 
but in others topologies this is not right.  
I propose, the polars tiles are not coast for trireme, its are not safe there 
at last if the topology is 
not the classic one (cylindrical) . Or best, trireme never are safe near polar 
tiles.

In divers topologies the poles can ave a interesting game play in the war if it 
are god done.
