Is there a known reason why the Darksaber was kept in the Jedi Temple?

Question

The TV series Star Wars: The Clone Wars introduced a new (but ancient) lightsaber known as Darksaber.

According to (canon) legend, this one of a kind lightsaber was allegedly created by and belonged to the the first ever Mandalorian to join the Jedi Order.

The Darksaber was an ancient and unique black-bladed lightsaber created by Tarre Vizsla, the first Mandalorian ever inducted into the Jedi Order, prior to 1019 BBY. The weapon was kept in the Jedi Temple after Vizsla's passing, but members of House Vizsla stole the saber in a conflict with the Jedi during the fall of the Old Republic. The Darksaber was passed down, generation to generation, by the ancestors of Pre Vizsla, who held onto the weapon even after the pacifist ideals of the New Mandalorians replaced the warrior ways of Mandalore.

However, after Terre Vizsla's death,, the Darksaber was kept by the Jedi, until it was stolen by House Vizla.

I have not seen much of The Clone Wars TV series and the Wookieepedia entry does not seem to say much about this conflict between the Jedi and Mandalorians of this era, or how and/or why Vizla was killed, but I was wondering if there are ANY explanations given as to why the Jedi would have kept the weapon and/or have not just freely have given it to House Vizla?

To better understand the context of my question, the Darksaber shows up again not only in Star Wars: Rebels and Darth Maul: Son of Dathomir, but also

The Mandalorian!

This prompts me to more deeply consider the weapon's abilities and if its kyber crystal could ever be aligned with the dark side of the Force, as

The Mandalorian has potential to fill in *some of the sequel trilogy's backstory, most noticeably the resurrection of Darth Sidious and/or the return of the Sith.

Now perhaps it is a "neutral" kyber crystal and anyone can use it, but I just feel like there is a lot of missing information in its backstory that seems to feed into a conflict between the Jedi (who normally do not hold onto objects, as Jedi are often encouraged or expected to make their own lightsabers at some point. In fact it's more likley for a Sith to steal and corrupt another's object) and the Mandalorians/House Vizla (as lightsabers are NOT traditional Mandalorian weapons, even though Mandalorians have used the Darksaber to conquer Mandalore during the Clone Wars).

Everything in the Darksaber's backstory is dancing around the contention of a Mandalorian vs being a Jedi and what this Darksaber actually is/does, which goes hand-in-hand with other aspects of The Mandalorian 1.08...

The Armorer tells Djarin that he must teach the Child and be his father, but eventually, he must also find the Child's creed in either it' species or the Jedi. The Child is then on a trajectory similar to Terre Vizla being caught between the creed of the Mandalorian and the Force (the Jedi/the Sith).

Answer 1

The Darksaber was a lightsaber created by Tarre Vizsla, a Mandalorian Jedi. therefore the Jedi had jurisdiction over it. Plus, it was considered by the Jedi to be an artifact of their past. The Darksaber was both a lightsaber and one created by a Jedi, so the Jedi had claim over it. We can assume it was probably used in history lessons too, since it was a relic of the Jedi's history.

Also no, the kyber crystal of the darksaber is not aligned with the dark side. No kyber crystal is naturally aligned with the dark side. Dark sider users must 'bleed' their crystals to create the red colour. So yeah, it was probably neutral.
