Well shoot - okay so sorry that Froststar's Loyalty kinda sucks, I just realized that some of the ages are wrong and stuff.
Swampstream is supposed to be reaching her 12th year of being alive when FROSTSTAR is BORN. But, in Froststar's Loyalty, she's an apprentice.
Whoops
PLEASE TAKE THE STUFF IN BLIZZARDFUR'S TRIALS AS FACT UNLESS STATED OTHERWISE ABOUT SWAMPSTREAM.
On other topics about the authenticity of Froststar's Loyalty, I SKIPPED A WHOLE SECTION ABOUT HER AND ASHPELT'S RELATIONSHIP. Sorry.
Most of the stuff in Froststar's Loyalty is accurate, like Foxfur leaving to ShadeClan and Gullstorm being killed and forgiving Froststar and giving her one of her lives, but all the Swampstream is kinda off.
Froststar is young to be a leader. She is currently about 40 moons (3.5 years) old in Blizzardfur's Trials. So I can't really do anything about that ¯\_(ツ)_/¯
Have a great day guys!
