The secrets have been updated on the first page. Regarding the teachers' roles, in order to make the game properly balanced, their votes were worthless, but they did not know that.
The 7 Horcruxes
1.
Marvolo Gaunt's Ring - because of the curse cast upon it, the ring will decrease the target’s chances of using their power effectively by 50%;
2.
Tom Riddle’s Diary - opens the Chamber of Secrets; whoever dares to mention the name of He-Who-Must-Not-Be-Named will be role blocked the next night;
3.
Helga Hufflepuff’s Cup - being under the Gemino Curse, the cup will make Voldemort’s vote worth twice the next day;
4.
Salazar Slytherin’s Locket - using the art of Necromancy and the locket, Lord Voldemort can summon an Inferius from the pool of dead players for a Day and a Night period, thus controlling both their vote and power;
5.
Rowena Ravenclaw’s Diadem - said to make its bearer wiser, it shall check the role of a living player;
6.
Harry Potter - Harry Potter can be lynched the next day;
7.
Nagini - the Dark Lord’s only trusted companion shall force its target to speak parseltongue (Insanification, different from that of Luna’s)
Voldemort can only choose a Horcrux on Night 1. For the rest of the nights, they will be hidden in the Night Polls and voted by all the players.
