Aquilas from the Battle of Teutoburg Forest

Origin
The Battle of Teutoburg Forest occurred in 9 A.D, between the Germanic tribes led by Arminius and the Roman Empire. Allied under an adopted Roman citizen and commander, Arminius knew all the legions tactics and could predict any possible attack. The raid caught the Roman army by surprise and dealt them a heavily devastating loss, over 16,000 soldiers. Afterwards, the Roman army never attempted to re-invade Germanic territory east of the Rhine River.

After the initial shock, the Romans slowly rebuilt for a revenge and conquer mission. In 16 AD, the emperor’s nephew Germanicus led a surprise assault on the neighboring tribes and continued to devastate them for years. During this time, his troops recovered two of the three legions’ eagles lost in the battle; the third was recovered 15 years later during the reign of Cladius. They were then placed together by Warehouse 3 inside the Temple of Mars Ultor to keep their war-oriented effects in check.

Effects
Each eagle is imbued with the same ability, to let the underdog utterly beat the enemy. The inferior side must place an aquila in the possession of the enemy it will fight, whether it will be through battle, subterfuge or public discrediting. The better group will suffer from a sudden lack of leadership, funds or resources while the lesser group will receive an influx of information and strategic coordination and can periodically launch surprise attacks on the enemy.

The effects have been noted to linger for a while with the old owners before moving on to the current owner. This explains why the Romans took years before retaliating and how the aquilas started to negatively affect the tribes after they were left in Germanic territory.
