If you require to take it, we will need something great in return, namely of technological knowledge. It is our imperative to learn, to understand, to create knowledge and to ultimately evolve as custodians. We do not care if you have vengeance to undertake against Humanity, we hold no moral high ground. But if you intend on putting every sentient species to extinction - including your brothers and yourselves, there is a conflict of ideology there.
To take the artifacts of interest would put a great indent on our Gatekeeper projects, our harvester, our Eradicator blueprint, our shield theories, and most importantly, the project Melia had agreed upon - the Triumvirate Gate Network.
It would be of great interests to us both if there was compensation of knowledge - perhaps a full insight into the jumping technology you have studied, especially when the Order's spotlight is already upon us. If they continue and our sterile environment is compromised, understand that they will have an easier time tracing you down. You may as well know one of our contingencies now that you have approached us with the desires and experiments: It is to jump the entire world into a calculated position. Hence the probes. They seek areas for the experimentation.
We can help you, but you must help us to help yourself. Provide us research to help protect us in fending off the aggressors that seek your trail, and you can take the samples. In doing so, we are able to provide future support to your operations. We cannot if we are chained down by limitations and an overwhelming force that awaits for us. I hope you understand why we cannot relinquish it immediately?
