Forum:Hero's bow?

I'm wondering, the Hero's bow in only in three games, under that name. Link acquired it in Termin. But how is that it's both Twilight Princess and Windwaker. Didn't one time-line not have a Link? Plus the in the title of the game, It says "Legend" which means that some things in the game are not in entirely accurate. The Series is also created by a man, which means he could have intended this, and just decided to use the split time-line theory.
