The Zygnian hunger for knowledge started to cloud their judgment. All of a sudden, everyone wanted to partake in this epic endeavor of interstellar gluttony. It was the next logical step for both the communal mind and each participating member. As mentioned earlier, they were human-like, but those similarities were only superficial, as they were vastly superior and transcended the cognitive levels of Earthlings.
The initial infatuation faded, as their innate reasoning intervened and started a global telepathic parley. A parley would, in human terms, involve two opposing sides trying to reconcile their differences. However, we cannot really comprehend the Zygnian multi-dimensional exchange, as we lack understanding of higher dimensions, telepathy, and all those phenomena we are so keen to attribute to supernatural. We could image a Zygnian as a composite entity occupying or interacting with multiple planes of existence: the material plane, a telepathic network of selves, and the inherently altruistic communal mind. Using astronomical terms, this pinnacle of biological evolution could be interpreted as a metaphorical syzygy of self, selflessness, and their planet of origin.
In their symbiotic relationship with Zygnus-Z5, this race of utopian beings resonated with their home world in harmony. They revered it with utmost respect. It was their ancestral mother, their source of wisdom, their cradle of life, and most of all, a living and breathing organism. Zygnus-Z5 and her inhabitants were two harmonics of a singular resonance.
Being able to engage in meaningful dialogues with planets, stars, and even galaxies is, for the lack of a better explanation, ethereal.
With their access to a vast cosmic well of information, the Zygnians and Zygnus-Z5 concluded their parley with a clear insight into problems pertaining to interstellar travel. The decision had been made to select a minimal crew of three most suited individuals and get them acquainted with TSD-1. One might assume that such endeavour would take many human years to finalize, but Zygnians had no perception of "learning". Their communal mind contained everything there is, was, or will be; they could summon the skills they needed from any member of the mind-network, including their home planet.
However, they still needed practical experience which they could only gain with physical practice. This posed a minor issue, as TSD-1 was a highly automated engineering masterpiece and required minimal maintenance. The projected time needed for the crew to gain practical experience and master the major systems of the vessel was merely one human week.
