The Library Of Course!

Regulus went straight to the Library, finding Hermione wasn't there, he decided to make the most of it and get some Tomes out. He looked into Advanced Charms, Intermediate Transfiguration, and Several Hevaily Deatailed and Comprehensive Guides to Jinxes, Hexes, and Curses and their Counter-Spells. These were not the only books ge got out, just the Largest, smaller ones were on the Subjects of Astronomy, Arithmancy, Ghoul Studies, Herbology, Alchemy.

He also took an interest in Magical Fauna, but decided to leave that for now. Looking at his Pocket Watch he Saw that an Hour had already passed and instead Decided to Go Pack. He'd Have to See Hermione Shortly before he left.

Regulus had finished in Packing in Half an Hour and had Left a Note with Ginny to pass on to Hermione. He then went to the Location of the Carriages that would be taking them to Durmstrang. He was about to Enter the Carriage that Held Ravenclaw Student Cho Chang, Slytherin Students Daphné Greengrass and Millicent Bulstrode, and Hufflepuff Students Penelope Clearwater and Cedric Diggory, when he abruptly stopped and looked one last Time at the Castle, Particularly Gryffindor Tower.

After passing the time with Cedric and Cho talkig about Quidditch, they finally arrived at the Durmstrang Institute. It was an Intimidating School for certain. 'No wonder Grindlewald came here!' Regulus thinks in his head. They were soon Greeted by A portion of the Student body with an Imposing Dark-Haired man, the Headmaster no doubt. The Students on the Other Hand, were likely The Schools Elite .
