A call to arms

Let it be known that on the morrow of the twentyth of the month of Iulius an epict battle of wit and might shall commence. Upon this date, and lasting for not less than three dawns, great men and boys alike shall meet heafod to heafod and attempt to complete a micel task.
If ye breosthord is forstrang and ye gemynd geryman then beran theself to the flitan.
