My take on Klaus/OC (occasionally maybe other rather short flings between TVD characters and OC). Starts around S03E12 (TVD) and hopefully extents to The Originals Season 5. Prepare for a slow and bumpy road, cause no true happy ending is achieved easily ;) (Oh and don't be confused, because it may look like Elijah/OC in the beginning - it's not. [Rating may change to M])

Esther didn't just need Elena Gilbert's blood to complete the spell to link her children, she needed another's. This person, however, lied much closer to the Mikaelson brothers' hearts. All it would take was one spell & the Mikaelson brothers' lives would forever change. United they stand, divided they fall. House Mikaelson. Always & Forever. Original Brothers/OC
