Under the influence of an especially strong barrel of Longbottom Leaf, Saruman decides to reexamine his campaign against Rohan. He elects to sacrifice his army of Uruk-hai & Dunlendings & the Palantir for a one-time space-time warp.
In exchange he gets the following team.
Feanor & his 7 sons
Fingolfin
Finrod Felagund
Beleg Strongbow
Ecthelion of the Fountain
Mablung of the Heavy Hand
& a couple of Elf-friends
Hurin Thalion
Beren Erchamion
Turin Turambar
Total of 16 First Age warriors.
Equipment: Turin gets Gurthang, Beleg gets Anguirel its twin, along with their usual set-ups. Everyone else gets their standard war gear. They are provided with horses and appropriate supplies.
Scenario: The Gank Squad teleports into Rohan 10 miles from Helm’s Deep. Grima Wormtongue briefs them on the operation. Rohirrim scouts spot them as they ‘port in and start riding back to the Deep to tell what they see. No interference from Treebeard or the Ents. Gandalf can run messenger but isn’t allowed to fight until one side is victorious. Once the squad gets within 1 mile of the fortress a barrier seals everyone inside until battle’s end.
Gank Squad victory is achieved by taking control of the Hornburg & loudly blowing said horn. Rohirrim victory is achieved killing every last member of the squad.
How does this go?
EDIT: If Gank Squad wins they’re told Eru will shower then with their hearts’ desires. This is to make Feanor actually be a team player instead of betraying Saruman or threatening to stab Fingolfin or any of the other things he’d likely do in-character.
