Minerva & Open (multiple responses welcome)!
Minerva found it necessary to keep herself well read in many subjects outside of her speciality. History was something she had always had an active interest in (both Wizarding and Muggle), and while the new exhibition on offer at the museum had some issues, Morgana held her place in the history texts. She had been a powerful witch, an Animagus and a Healer, all of which could take central stage in the exhibition. However, there was also no denying her use of dark magic and her rivalry with Merlin. Romanticising such characters did not bode well with her and she hoped the exhibition was a well-rounded and accurate portrayal.
Aside from the new exhibit, there were other tidbits in the museum that she wished to review. She had arrived just as the initial socialising had finished, taking her seat to listen through the various speeches. Narcissa carried herself well through hers, but Minerva was thankful that such things did not drone on. The meal that followed passed in a flurry of pleasantries and small talk--though there was one mention of her Order of Merlin and her cutting body language stopped that conversation escalating much further.
With the dinner done, she had chosen to avoid the tours as she much preferred to go at her own pace and study the artefacts on offer. When the initial surge towards the Morgana exhibit eased, she made her way for it.
