The terms Lost Technica 《秘奥義【ロスト・テクニカ】》 and Last Crest 《魔道極法【ラスト・クレスト】》 are
quite ambiguous, since they are usually mentioned together with the
explanation for being a member of Trinity Seven.

In chapter 17, both terms are used one after another near the end of the
chapter. This is from just before Liese activated her trump card.

> ["To be a Trinity Seven means that you've acquired the _Lost Technica_ in
> your particular archive." \- Liese](https://i.stack.imgur.com/0kcMz.png)
> [[Japanese version]](https://i.stack.imgur.com/xRCBi.png)

When Liese activated her trump card, and Sora (the human form of Astil
grimoire), warned Arata about the magic being used.

> ["This is Avaritia's _Lost Technica_ , the _Last Crest_ ..." \-
> Sora](https://i.stack.imgur.com/bzG1X.png)
>
> "That's right. It's _**Baal Peor**_ " \- Liese

Then in chapter 19, the condition to be part of Trinity Seven is reiterated,
but this time with _Last Crest_ in place of _Lost Technica_ :

> "The Trinity Seven are the top class magi of each of the seven deadly sins,
> right?" \- Arata
>
> ["Correct. We are the ones who have mastered the _Last Crest_ of each
> archive" \- Lilith](https://i.stack.imgur.com/g3fTz.png) [[Japanese
> version]](https://i.stack.imgur.com/1UVNE.png)

I have two questions regarding these two ambiguous terms:

  1. What is the difference between them?

  2. Regardless whether they refer to different concept or not, does _Lost Technica_ implies _Last Crest_ and vice versa?

(Please back up your answer with primary sources, rather than secondary
sources like Wikipedia or Wikia. You can use them as starting point, though).
