THE PIT AU is an alternative universe which takes canon characters from all 7 seasons of Beyblade Burst and continues 3 years after QS. The OG story doesn't change in TPAU, it stays the same due to the new characters not becoming relevant until after S7. TPAU follows mostly the anime's plot, but the backgrounds of characters and certain events are assumptions based on manga + anime lore. TPAU uses the "QuadStrike Timeline": - confirmed by Hanami in S7: Bel VS Pax's fight happens only 3 years after Red Eye VS Valt fight.
