[Returning player from Launch]

Greetings Tenno Primes, My name is Skallagrimsson I am returning to warframe from the era of its begginings. If anyone has any links to sources that would help me sync with the current state of the game, such assistance would be much appreciated.  I request that if such a topic has been discussed elsewhere, that you would spare me thy criticisms and kindly direct me towards the enlightenment of which I seek. Your cooperation ismuch appreciated and may your drops be forever blessed and deserving of thy commitment and efforts.
