Remnant's Dragjiu

Just after team RWBY has finished initiation a massive vortex opens in the sky and a single large crystal slams deep into the emerald forest then as quickly as the vortex opens it closes Ozpin tells the students to help the teachers find where that crystal landed. What will they find? What was that strange vortex that appeared? Why did that crystal come out of that portal?
