Andrew changed his form to another person just in case, he don't want to deal with unnecessary trouble. His presence caused Ragnarok faster than he thought. Even though he took away teh eternal flame somehow surtur gained power and destroyed Asgard.
Andrew appeared in nellavidar and controlled the dwarf there. He commanded the dwarf to make weapkns while he used his telekinesis to hold the star gate open for the forge. After many blue porints are completed ranging from axes, swords, spears even storm breaker Andrew is satisfied and left the place.
He saw everything is back on course, the asgardians went to another planet with all the population in a space ship and everyone except hela are there even Odin. This surprised him.
Looks like plot corrected itself Odin's death isn't destined yet. Andrew shook his head and returned to his world. He healed hela and connected her source of power to him. Which managed to wake her up. Upon waking up she kneeled in front of him and greeted him in a polite way.
He returned from his dimension and told both of them to get along. He returned downstairs and asked saw Nicholas and pernelle getting ready to visit the French market of wizarding world. He heard it's very grand, well ordered and nice compared to other countries ministry of magic.
Andrew, Hannah, Nicholas and pernelle goes to the ministry of magic then to the French shopping district. Andrew is amazed by the architecture, everything is well organised and built in an order unlike other ministries and shopping districts that are built in random.
Andrew said he'll take a look around while Hannah and pernelle are immersed in clothes, jewellery and other things. Nicholas first rejected but after Andrew asked him again and again he let him go after taking a word not to explore too far from here.
Andrew executed his plan, he let kaguya and hela out and awakened kaguya's magic. Hela already has magic in her. He manipulated the magic string that bounded kaguya when she awakened maguc and let it biound to Hogwarts which he also did the same to kaguya.
He arranged a scene here about two girls being chased by a dark wizard who wanted to abduct them and when their magic rioted and Andrew attacked using his obscurus he escaped. After doing this he quickly called Nicholas using the locket they gave him to signal them when in trouble.
Nicholas immediately rushed there to see Andrew who is panting as he used the obscurus in real to create the fatigue, and two girls who are there looking vigilant. Andrew explained about seeing them being chased by a dark wizard.
After few moments of explaining Nicholas looked at the two girls who are there looking vigilantly at them and then at Andrew. He sighed and reported this to the ministry of magic. Only a few of them recignised Nicholas flamel and pernelle.
After they used magic to revert the actions they exactly found the same scene that Andrew said and reassured the girl's that they'll catch the dark wizard. They also asked who are they while the two girls said they're orphans that are chased by this dark wizard and appeared here somehow.
The staff don't what to do abott these two girls while Andrew asked Nicholas who finished lecturing him about using obscurus and wandering alone. He asked Nicholas about the two girls and asked him whether they can take care of then for the time being.
Although Nicholas felt it's troublesome and something amiss but after Andrew pursuaded Nicholas about his life outside ad told him that he don't want to see them suffer like he did he accepted the two girls to stay with them temporarily.
At this time almost all preparations in Hogwarts are done but then the book of admission again wrote two names, Emma frost and hela frost. When Andrew and Nicholas appeared in the shop again pernelle and Hannah looked at the two girls and then at Nicholas with questioning looks.
After Nicholas told them about the two girls pernelle eyes softened and she hugged the two saying she'll take good care of them while Hannah pinched Andrew's ears and lectured him for a few minutes. Andrew stayed silent while coaxing Hannah.
