While on the trail for one of the Retention Stones, hidden by Caelus Cr, Andy Ld was attacked by a stranger who left his teddy bear Rajesh in a very sorry state. Overcome with unquenchable fury, only Sue’s timely intervention managed to make him see reason. Under her spell, he agreed to return to the Academy… but only until he’d got his strength back.
Andy Ld is a legendary character who is only available by carrying out missions connected with him. To obtain this character, you must unlock his last mission before July 14rd at 11.59pm (GMT + 2:00).
My theory is that the missions are all references to the Harry Potter Universe.
Beyond the Diary - HP and the Chamber of Secrets.
In the rings of fate - HP and the half-blood prince
The echoes of the Locket - HP and the deadly hallows
Will lead you thanks to the goblet - HP and the Goblet of fire
To the site of the retention stone - HP and the Philosopher's stone.
This theory has further support, as previosly pointed out, the new mission spells Doloris Kedavra backwards.
Doloris = Doloris Umbridge
Kedavra = Avada Kedavra.
