sellar protects stella because stella hasn't adapted and evolved to have any defences that can ward enemies away...once day stella was attacked by a odd eagle, stellar leapt right between the two and rammed the eagle but the eagle grabbed stellars arm and ripped it clean off, stellar in defence stung the eagle, the eagle was paralyzed by the sting and soon died stella came up to stellar and addressed the damage and licked the wound ( this cleans it and lowers the chance of an infection ) as stellar looked at stella and out her head on her back trying to stomach the pain then days later stella was gone and stellar was desperate to find stella...to this day they are still separated
