if someone has a link or explanation as to why TESV will be in Skyrim it would be much appreciated.

There has been no official statement of any kind. All the speculation surrounding a Skyrim setting has been based upon some trademark applications Bethesda took out in 2006. All further speculation to the official thread, please: http://www.gamesas.com/index.php?/topic/1092229-official-tes-v-speculation-thread-number-31/
